Description

Title of the invention: AUTOMATIC TELESCOPIC POLE AND CLEANING SYSTEM COMPRISING SUCH A POLE Technical field of the invention

[0001] The present invention relates to a telescopic pole and a cleaning system comprising such a pole. It applies, in particular, to cleaning devices used in the field of window maintenance and cleaning. State of the art

[0002] Window cleaning requires the intervention of a maintenance agent using a manual cleaning device. Since some windows are located at significant heights, the maintenance agent is required to use a ladder or a lift to access these different heights. However, such systems for accessing heights present a danger to the user.

[0003] Prior art solutions describe the use of telescopic poles to access suitable window heights for cleaning. However, the length of the poles, which can be modified thanks to the telescopic nature, is only manually adjustable. Thus, adjusting the length of the pole requires several handling operations, resulting in a loss of time for the maintenance agent and a lack of maneuverability and practicality.

[0004] No prior art solution allows easy maintenance of windows at significant heights in a manageable and practical manner. Summary of the invention

[0005] The present invention aims to remedy all or part of these drawbacks.

[0006] The present invention makes it possible, by combining an automatic telescopic pole with a window cleaning device to form a cleaning system, to easily access window heights. In particular, the maintenance agent cleaning a window quickly and automatically and conveniently adapts the length of the telescopic pole. Brief description of the figures

[0019] The present description is given without limitation, each characteristic of an embodiment being able to be combined with any other characteristic of any other embodiment in an advantageous manner.

[0020] The expression "and / or", as used herein and in the claims, is to be understood to mean "either or both" of the elements so conjoined, i.e., elements that are present conjunctively in some cases and disjunctively in other cases. Multiple elements enumerated with "and / or" are to be interpreted in the same way, i.e., "one or more" of the elements so conjoined. Other elements may optionally be present, other than the elements specifically identified by the "and / or" clause, whether or not related to those specifically identified elements. Thus, by way of non-limiting example, a reference to "A and / or B", when used in conjunction with open language such as "comprising" may refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (possibly including elements other than A); in yet another embodiment, to A and B (possibly including other elements); etc.

[0021] As used herein in the description and in the claims, "or" is to be understood as having the same meaning as "and / or" as defined above. For example, when separating elements in a list, "or" or "and / or" is to be interpreted as inclusive, i.e., the inclusion of at least one, but also more than one, number or list of elements, and, optionally, additional elements not listed. Only terms clearly indicating the contrary, such as "only one of" or "exactly one of", or, when used in the claims, "consisting of", refer to the inclusion of only one element of a number or list of elements.

[0022] As used in this specification and in the claims, the expression "at least one", with reference to a list of one or more elements, is to be understood to mean at least one element selected from one or more elements in the list of elements, but not necessarily including at least one of each element specifically listed in the list of elements and not excluding any combination of elements in the list of elements. This definition also allows for the optional presence of elements other than the specifically identified elements in the list of elements to which the expression "at least one" refers, whether or not related to those specifically identified elements.Thus, by way of non-limiting example, "at least one of A and B" (or, equivalently, "at least one of A or B", or, equivalently, "at least one of A and / or B") may refer, in one embodiment, to at least one, optionally including more than one, A, without B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, without A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.

[0023] In the claims, as well as in the description below, all transitional expressions such as "comprising", "including", "carrying", "having", "containing", "involving", "holding", "composed of", and the like, are to be understood as being open, i.e., as meaning including, but not limited to. Only the transitional expressions "consisting of" and "consisting essentially of" are to be understood as closed or semi-closed transitional expressions, respectively.

[0024] We recall here the following definitions:

[0025] The term "telescopic" refers to an object comprising at least two elements capable of sliding relative to each other and in particular one within the other. In other words, one element forms a slide and the other forms a slider.

[0026] The term "automatic" refers to an element whose movement is achieved by mechanical means without human intervention. In particular, such mechanical means are powered by electrical energy.

[0027] The term “pane” means a substantially smooth surface, for example made of glass. For example, such a surface is: - substantially vertical or - inclined, preferably having an angle of inclination relative to the ground of between 45° and 90°.

[0028] The term "washing water" designates water containing maintenance products suitable for cleaning and known to those skilled in the art. Preferably, such products are suitable for cleaning windows and have, for example, degreasing properties.

[0029] The term "mobile" designates an element having at least two degrees of freedom, for example in translation. For example, the translational movement allows one element to slide relative to another element.

[0030] The term "activation and / or deactivation means" designates an electronic component or software, configured to emit a positive command corresponding to an activation or deactivation action or only a positive command for one of these actions, the other action corresponding to an absence of command emitted.

[0031] The term "roller" designates, for example, an element in the form of a truncated cylinder having a circular section, but can also correspond to an element having a section of any shape, for example, octagonal. Preferably, such a section is generally circular. A friction roller is in particular known to those skilled in the art and comprises a coating capable of carrying out mechanical friction on a surface to be cleaned, such as a set of friction fibers.

[0032] The term “mobile” designates an element having at least two degrees of freedom, for example in rotation.

[0033] Throughout the description, the term "upper" refers to everything that is at the top in Figures 1 to 11 which corresponds to the normal configuration of use of the device, and "lower" refers to everything that is at the bottom in Figures 1 to 11. The terms "vertical" or "height" are derived from these definitions. In [Fig.l], a pole has a longitudinal axis called "axis A", such an axis extending along a largest dimension of the pole and corresponding to the length of the pole. Axis A corresponds to a translation axis, a movement carried out during the sliding of certain elements of the pole.

[0034] It should be noted from now on that the figures are not to scale.

[0035] In [Fig.l], which is not to scale, we see a schematic view of a mode embodiment of the pole 100 which is the subject of the present invention. It is noted that the pole 100 and a cleaning device 105 form a cleaning system 1000 for a window. For example, the pole has a cross-section in the shape of a circle or a hexagon. Preferably, the pole is in the shape of a truncated cylinder.

[0036] It is noted, in [Fig.l], that the telescopic automatic pole 100 is a support for a cleaning device 105 for a window (not shown). The automatic pole 100 comprises: - a lower arm 110 for gripping a user; - a first arm 115 movable in sliding relative to the lower arm 110; and - a means 125 for sliding the first arm 115 movable relative to the lower arm 110.

[0037] We observe, in [Fig.l], that the sliding of the first arm 115 is represented by a pair of arrows: - the solid arrow represents the sliding movement carried out to deploy the first arm 115, such deployment corresponding to an increase in the length of the pole 105 and - the dotted arrow represents the sliding movement carried out to retract the first arm 115, such retraction corresponding to a reduction in the length of the pole 105.

[0038] In embodiments, such as that shown in [Fig.l], the first arm 115 is connected to the cleaning device 105 by a connection element 120. The connecting element 120 is, for example, a connector (not shown) adapted to connect the first arm 115 to the cleaning device 105 or comprises another sliding arm 121 mentioned in the remainder of the description.

[0039] In embodiments, such as that shown in [Fig.l], the sliding means 125 comprises: - a 130 wheel, - a 135 drive motor and - a means 140 for activating and / or deactivating the drive motor 135.

[0040] It is noted that the wheel 130 is driven in rotation by the drive motor 135. Such rotation causes the first movable arm 115 to slide. Preferably, the motor 135 is incorporated into the wheel 130.

[0041] The rotation of the wheel 130 is around an axis (not shown), called the axis of rotation, preferably perpendicular to the axis A of the pole 100. We observe, in [Fig.l], that the rotation of the wheel 130 is represented by two curved arrows: - the curved black arrow represents the rotation allowing the deployment of the first arm 115 and corresponding in particular to an increase in the length of the pole 105, and - the curved white arrow represents the rotation allowing the retraction of the first arm 115 and corresponding in particular to a reduction in the length of the pole 105.

[0042] In embodiments, such as that shown in [Fig.l], the activation and / or deactivation means 140 is electrically connected to a switch 167. In other words, the switch 167 activates the raising or lowering of the first arm 115.

[0043] In embodiments, such as that shown in [Fig.l], the pole 100 comprises: - a 112 hoop and - a rigid branch 113 fixed to the hoop 112.

[0044] It can be seen in [Fig.l] that the strapping 112 is secured to an upper end of the lower gripping arm 110. The strapping 112 is fixed to the rigid branch 113, for example, by welding.

[0045] It is noted that the rigid branch 113 supports the wheel 130 driven in rotation. Such a rigid branch 113 keeps the wheel 130 resting on the first movable arm 115. In particular, the rigid branch 113 and wheel 130 assembly participates in guiding the sliding movement of the first arm 115.

[0046] In embodiments, such as that shown in [Fig.l], an electric wire 141 for supplying power to the motor 135 incorporated in the wheel 130 extends along the internal volume delimited by the rigid branch 113. In these embodiments, the rigid branch 113 has a longitudinal hollow volume. In variants, such an electric wire is external to the rigid branch 113.

[0047] In embodiments, such as that shown in [Fig.l], the sliding means 125 of the first movable arm 115 further comprises an additional wheel 132 driven in rotation.

[0048] In these embodiments, the wheel 132 is driven in rotation by an additional drive motor 137. It is noted that the rotation of the additional wheel 132 participates in the sliding of the first movable arm 115 disposed between the two wheels, 130 and 132. In variants (not shown), the additional wheel 132 is driven in rotation by the sliding of the first arm 115 and is thus adapted for guiding the first arm 115 during sliding.

[0049] Preferably, when the wheel 132 is driven in rotation by the additional drive motor 137, the activation and / or deactivation means 140 of the drive motor 135 is common to the additional drive motor 137. In variants, the additional drive motor 137 is connected electrically to an activation and / or deactivation means separate from the activation and / or deactivation means 140.

[0050] In embodiments, such as those shown in [Fig.l], the pole 100 comprises an additional rigid branch 114 fixed to the hoop 112. It is noted that the additional rigid branch 114 supports the additional wheel 132 driven in rotation and keeps the additional wheel 132 resting on the first movable arm 115. In particular, the force exerted on one wheel, 130 or 132, is opposite the force exerted on the other wheel, 130 or 132.

[0051] Thus, during sliding, the holding and guiding of the first arm 115 are improved. The first arm 115 held between the two wheels, 130 and 132, respectively supported by the rigid branches, 113 and 114, therefore has optimal stability and resistance to mechanical stresses.

[0052] In embodiments, such as that shown in [Fig.l], at least one element among the lower gripping arm 110 and the first movable arm 115 has at least one longitudinal section 116 for passing electrical power supply wires 118. It is noted that the power supply wires are, for example, power supply wires connected to the cleaning device 105. In embodiments not shown, when the pole is electrically connected to a mains socket, the power supply wires passing in the longitudinal section 116 are the power supply wires of the drive motor 135.

[0053] In embodiments, such as that shown in [Fig.l], the lower gripping arm 110 comprises at least one longitudinal element 151 of a shape complementary to the hollow volume delimited by the longitudinal section 116. In particular, such a longitudinal element is in contact with a portion opposite the portion of the longitudinal section 116 along which the electrical wires extend. It is noted that, during sliding, the longitudinal element 151 slides along the longitudinal section 116. Thus, the longitudinal section 116 participates in guiding the sliding of the first movable arm 115.

[0054] In embodiments, such as that shown in [Fig.l], the first movable arm 115 comprises another hollow longitudinal section 152 extending at least partially over the length of the first arm 115. In particular, the lower gripping arm 110 further comprises another longitudinal element 153 of a shape complementary to the hollow volume delimited by the other longitudinal section 152. It is noted that, during sliding, the other longitudinal element 153 slides along the other longitudinal section 152. Thus, the longitudinal section 152 participates in guiding the sliding of the first movable arm 115. Preferably, when the first movable arm 115 is a truncated cylinder, the two longitudinal elements, 151 and 153, are diametrically opposed. Thus, the guiding of the sliding of the first arm 115 is optimized.

[0055] In embodiments, such as that shown in [Fig.l], the connection element 120 further comprises a second arm 121 movable in sliding relative to the first movable arm 115.

[0056] In these embodiments, it is noted that the pole 100 further comprises a second means 126 for sliding the second movable arm 121 relative to the first movable arm 115. It is noted that the second sliding means 126 comprises: - at least one second wheel 131, - a second drive motor 136 and - a means of activating and / or deactivating 241 the second drive motor 136.

[0057] It is noted that the wheel 131 is driven in rotation by the drive motor 136. Such rotation causes the second movable arm 121 to slide. Preferably, the motor 136 is incorporated into the wheel 131.

[0058] The rotation of the wheel 131 is around an axis (not shown), called the axis of rotation, preferably perpendicular to the axis A of the pole 100.

[0059] In embodiments, such as that shown in [Fig.l], the activation and / or deactivation means 241 is electrically connected to the switch 167. In other words, the switch 167 activates the raising or lowering of the second arm 121. Preferably, the switch 167 also activates the raising or lowering of the first arm 115.

[0060] In embodiments, switch 167 activates: - firstly, the raising of the first arm 115 then - secondly, the raising of the second arm 121, according to the user's needs.

[0061] In variants (not shown), the switch for activating and / or deactivating the raising or lowering of the first arm 115 and the switch for activating and / or deactivating the raising or lowering of the second arm 121 are distinct.

[0062] In embodiments, such as that shown in [Fig.l], the pole 100 comprises: - a second hoop 162 and - a rigid branch 163 fixed to the second hoop 162.

[0063] It can be seen in [Fig.l] that the second strapping 162 is secured to an upper end of the first movable arm 115. The second strapping 162 is fixed to the rigid branch 163, for example, by welding.

[0064] It is noted that the rigid branch 163 supports the second wheel 131 driven in rotation. Such a rigid branch 163 keeps the wheel 131 resting on the second movable arm 121. In particular, the rigid branch 163 and second wheel 131 assembly participates in guiding the sliding movement of the second arm 121.

[0065] In embodiments, such as that shown in [Fig.l], the second sliding means 126 of the second movable arm 121 further comprises a second additional wheel 166 driven in rotation.

[0066] In these embodiments, the second additional wheel 166 is driven in rotation by a second additional drive motor 168. It is noted that the rotation of the second additional wheel 166 participates in the sliding of the second movable arm 121 disposed between the two wheels, 131 and 166. In variants (not shown), the second additional wheel 166 is driven in rotation by the sliding of the second arm 121 and is thus adapted for guiding the second arm 121 during sliding.

[0067] Preferably, when the second additional wheel 166 is driven in rotation by the second additional drive motor 168, the activation and / or deactivation means 241 of the second drive motor 136 is common to the second additional drive motor 168. In variants, the second additional drive motor 168 is electrically connected to an activation and / or deactivation means distinct from the activation and / or deactivation means 241.

[0068] In embodiments, such as those shown in [Fig.l], the pole 100 comprises a second additional rigid branch 164 fixed to the second hoop 162. It is noted that the second additional rigid branch 164 supports the second additional wheel 166 driven in rotation and keeps the second additional wheel 166 resting on the second movable arm 121. In particular, the force exerted on one wheel, 131 or 166, is opposite the force exerted on the other wheel, 131 or 166.

[0069] Thus, during sliding, the holding and guiding of the second arm 121 are improved. The second arm 121 held between the two wheels, 131 or 166, respectively supported by the rigid branches, 163 and 164, therefore has optimal stability and resistance to mechanical stresses.

[0070] In embodiments, such as that shown in [Fig.l], the pole 100 comprises an autonomous power supply 119. Such a power supply is electrically connected, for example, by electrical wires, to the elements of the pole 100, such as: - the activation and / or deactivation means, 140 and 241, - the drive motors, 135, 137, 136 and 138 and

[0071] - winders 117 and 123 mentioned in the remainder of the description.

[0072] For example, such an autonomous power supply 119 is a battery.

[0073] In embodiments, such as that shown in [Fig.l], the pole further comprises an automatic reel 117 for electrical wires 118 supplying the cleaning device 105. It is noted that the reel 117 is arranged on a lower end of the lower gripping arm 110.

[0074] In embodiments, such as that shown in [Fig.l], the battery 119 is electrically connected, by electrical wires 127, to the reel 117 of electrical wires 118 supplying the cleaning device 105.

[0075] In embodiments, the battery 119 is also electrically connected to the automatic winder 123 of electrical wires 124 supplying the second rotation means 126. Preferably, the winders, 117 and 123, are independent. More preferably, the winder 123 has a smaller size than the winder 117. Such a difference in size is justified since the length of the electrical wires 124 to be wound is less than the length of the electrical wires 118 to be wound.

[0076] In embodiments, such as that shown in [Fig.l], the electrical wires 118 supplying the cleaning device 105 extend along longitudinal sections 116, preferably aligned or slightly offset along the axis A, and included respectively in the lower gripping arm 110 and the first arm 115. It is noted, in [Fig.l], that such electrical wires 118 also extend along a longitudinal section included in the second arm 121.

[0077] In embodiments, such as that shown in [Fig.l], the electrical wires 124 supplying the second rotation means 126 extend along longitudinal sections 116, preferably aligned or slightly offset along the axis A, and included respectively in the lower gripping arm 110 and the first arm 115.

[0078] In embodiments, such as that shown in [Fig.l], the wires 127 connecting the battery 119 to the reel 117 are guided, at the lower part of the lower gripping arm 110, by a guide wheel 128. Preferably, such a guide wheel 128 is fixed at the lower part of the lower gripping arm 110 by means of a rod 129. More preferably, the rod 129 is removable.

[0079] In embodiments, such as that shown in [Fig.l], the wires 127 of the battery 119 are also connected to, and therefore supply electricity to, the winder 123 of electric wires 124 supplying the second rotation means 126. Preferably, the wires 127 of the battery 119 are guided by the guide wheel 128.

[0080] In embodiments, such as that shown in [Fig.l], a switch 133 for activating and / or deactivating the cleaning device 105 is included in the pole 100. Preferably, such a switch 133 is connected to the battery 119 and allows the activation or deactivation of the electrical power supply to the cleaning device 105 provided by the electrical wires 118.

[0081] The embodiments and variants set out for the elements of [Fig.l] are similar to those of the elements of [Fig.2] having the same numbering.

[0082] In embodiments, such as that shown in [Fig.l], the pole 100 further comprises a handle 111 called a “pressure handle”. It is noted that such a handle is fixed in the upper half of the gripping arm 110.

[0083] It can be seen in [Fig.l] that the pressure handle 111 comprises an arm 169 and a sub-handle 161. Preferably, a section of the handle 161 is a semicircle. It can be noted that the arm 169 is a pressure arm. In particular, the lever arm effect is obtained when the user holding the gripping arm 110 with one hand pushes the handle 161 with the other hand and in a movement directed towards the pole.

[0084] In embodiments, such as that shown in [Fig.l], the pressure arm 169 comprises a housing suitable for the insertion of a removable battery 119 for electrical energy.

[0085] In embodiments, the pressure handle 111 is foldable. Preferably, the pole comprises a hollow housing of a shape complementary to the pressure handle. For example, the folding of the pressure handle 111 is achieved by pivoting. In other words, the pressure handle 111 is fixed to the gripping arm 110 by a pivot connection. For example, a button present on the handle, known to those skilled in the art, is capable, for example according to a pressed or non-pressed configuration, of authorizing or blocking the pivoting responsible for the folding of the pressure handle 111.

[0086] In embodiments, such as that shown in [Fig.l], the pressure handle 111, and in particular the pressure arm 169, is fixed to the strapping 112.

[0087] In embodiments (not shown), the pole further comprises a strap for attaching a part of a user's body. In particular, such an attachment strap is attached to the gripping arm 110. Preferably, the part of the user's body to which the strap is attached is the waist or hip circumference. Thus, the total weight of the pole topped with a cleaning device is distributed not only over the user's hand holding the gripping arm 110 but also over the part of the body to which the strap is attached. The user's hand holding the gripping arm 110 is therefore relieved of part of the weight of the pole and cleaning device assembly.

[0088] The following embodiments and associated characteristics are set out in a non-limiting manner and correspond to preferred embodiments. In particular, the pole 100 shown in [Fig.l], preferably consists of three sliding arms. The first arm 110 is called a holding arm and allows sliding of the other two arms, 115 and 121. The holding arm 110 is provided along its length with another so-called pressure arm 169, this allowing pressure to be exerted on the entire pole 100 deployed by the user. The end of this arm 169 is provided with a semi-round handle 161. The interior volume of the pressure arm 169 is provided for inserting a removable battery 119 for electrical energy. Preferably, the pressure arm 169 can be folded along the holding arm 110, for example, by a pivot connection linking one end of this pressure arm 169 and the holding arm 110. The three arms, 110, 115 and 121, are provided inside their volume with two curved parts, 116 and 152, allowing the passage of electrical energy wires and serving as a guide for the sliding of the arms, 110, 115 and 121. These curved parts, 116 and 152, are face to face along an arm, 110, 115 or 121.On the sliding side of the arms, 115 and 121, there is provided a circle, 112 and 162, provided with so-called compression arms, 113 and 114 or 163 and 164, in order to press on the rollers 130 and 132 or 131 and 166. The compression arms, 113 and 114 or 163 and 164, are curved allowing to envelop a third of the sliding arms, 115 and 121. The battery 119 allowing to supply the electrical energy is connected directly to the circle 112 then by an electric wire in the compression arms, 113 and 114 and towards rotation rollers, 130 and 132. The rotation rollers, 130 and 132, are provided with motors, 135 and 137, inside, such motors allowing the rotation of the rollers, 130 and 132. At the end of the holding arm 110 is provided a roller 128 fixed by a removable rod 129 as well as two automatic reels, 123 and 117, each independent and also removable. The reel 123 is smaller than the other reel 117.An electrical wire 127 for power is provided from the battery 119 to the caster 128 and supplies the two reels, 117 and 123. An electrical wire 124 from the reel 123 is fixed on the strapping 162 and supplies the rotation casters, 131 and 166. Another electrical wire from the reel 117 to the end of the bottom of the arm 121 is provided to supply a cleaning device 105. These two wires, 118 and 124, unwind and rewind from the reels, 117 and 123, according to the length determined by the user. These two wires, 118 and 124, are inserted into the curved part 116 of the arms, 110, 115 and 121. The handle 161 at the end of the pressure arm 169 is provided with a switch 167 for raising and lowering the sliding arms, 115 and 121. Another switch 133 is present for the power supply wire 118, for continuous use of the external cleaning device 105.A strap (not shown) is provided to relieve the weight of the system 1000 deployed by the user on the arm 110. Thus, an automatic pole made by electrical manipulation is provided for a desired height without effort.

[0089] [Fig. 2], which is not to scale, shows a schematic view of an embodiment of the pole 200 which is the subject of the present invention. It is noted that the pole 200 and a cleaning device 105 form a cleaning system 2000 for a window.

[0090] It is noted, in [Fig.2], that the telescopic automatic pole 200 is a support for a cleaning device 205 for a window (not shown).

Similarly, the waste wash water suction pipe 202 comprises three pipe portions each internal to a lower gripping arm 210, to a first movable arm 215 and to a second movable arm 221 of a connection element 220. For a pipe, 201 and / or 202, it can be seen that the portions are connected two by two to each other by sealed connectors, 204 and 207.

[0092] Preferably, the injection pipe 201 for washing water and the suction pipe 202 for used washing water respectively have: - an upper end fixed to the upper end of the second movable arm 221 and - a lower end fixed to the lower end of the lower gripping arm 210.

[0094] In embodiments, such as that shown in [Fig.2], the wash water injection pipe 201 is connected, on a lower portion, to a wash water supply pipe 211 connected, for example, to a water tank.

[0095] In embodiments, such as that shown in [Fig.2], the pole 200 further comprises a lever 206 for injecting wash water into the injection pipe 201. Preferably, such a lever 206 regulates the injection of wash water via the pipe 211.

[0096] In embodiments, such as that shown in [Fig.2], the lever 206 is present in the lower part of the lower gripping arm 210.

[0097] In embodiments, such as that shown in [Fig.2], the suction pipe 202 for waste wash water is connected, in the upper part, to the cleaning device 205 via a connecting pipe.

[0098] In embodiments, such as that shown in [Fig.2], the suction pipe 202 for waste wash water is connected, in the lower part, to a flexible suction pipe 209. For example, the flexible suction pipe 209 is connected to a waste water tank.

[0099] In embodiments (not shown), the pole comprises a telescopic hollow conduit for the passage of the two telescopic internal conduits for injecting and sucking water. In particular, the two internal conduits are separate. The hollow conduit extends along the longitudinal axis (not shown) of the pole 200.

[0100] Note, in [Fig.2], that the electrical supply wires are not shown.

[0101] The following embodiments and associated features are set forth in a non-limiting manner and correspond to preferred embodiments. The pole 200 allows cleaning at height and is adjustable to a defined height. The pole 200 comprises, in its interior volume 202, a water injection 201 as well as the water suction 202. The pole is composed of several lengths made by pole arms, 210, 215 and 221. In particular, a fixed holding arm 210 as well as two telescopic arms, 215 and 221. The fixed arm is held by the user while the other two arms, 215 and 221 are provided to reach the intended length in height. The interior of the arms, 210, 215 and 221, are hollow 202. The holding arm 210, held by the user, is provided inside for the sliding of the other two arms, 215 and 221. A sealing element connects two sliding pipe sections, 201 and 202, with each other.Inside the holding arm 210 as well as the two sliding arms, 215 and 221, a hollow and rigid sliding water injection tube 201 is provided. The upper end of the tube 201 and the lower end of the tube 201 are respectively fixed to the upper end of the arm 221 and the lower end of the holding arm 210 for sliding. The lower end of the tube 201 present in the holding arm is plugged. Sealed connections, 204 and 207, are provided for sliding of the pipes, 201 and 202. The connection 208 is provided on the sliding arm 221 at the end with a cleaning device 205 comprising water injection and suction. The holding arm 210 is provided with a pressure arm 111 for its maintenance and strong pressure on the entire deployed pole 200. This 111 pressure arm is removable with user locking.The holding arm 210 is provided with a lever 206 for regulating the water to be injected outside of it. This lever 206 is connected to the injection pipe 201 at . the inside of the holding arm. The injection pipe 201 is connected to a flexible hose for connection to a device intended for injecting water 205 externally. The arms, 210, 215 and 221, of the pole 200 are hollow and are suitable for suction 202 of waste water. The lower end of the holding arm 210 is connected to a flexible low suction pipe 209. All the connection elements of the pole 200 are sealed at the sliding level, in particular the injection pipes 201, suction 202 and the arms, 210, 215 and 221. Thus the pole 200 is suitable for being connected to two devices allowing the injection and suction of water. A connector 208 on the pole 200 comprising an orifice allowing the passage of the pipe for injecting water towards the cleaning device 201.

[0102] In [Fig.2], we observe a cleaning system 2000 comprising a pole 200 and a device 205 for cleaning by injecting wash water and suctioning used wash water.

[0103] Preferably, the cleaning system 2000 comprises a cleaning device, 1100, 1200, 1300, 1500 or 1600 as mentioned in the remainder of the description. In other words, the cleaning device 205 is preferably one of the cleaning devices chosen from the cleaning devices 1100, 1200, 1300, 1500 or 1600.

[0104] It is noted that, in Figures 3, 6, 9 and 10, the circulation of wash water is represented by a solid arrow and the circulation of waste water is represented by a dotted arrow.

[0105] [Fig. 3], which is not to scale, shows a schematic view of an embodiment of the cleaning device 1100 capable of being coupled with a pole which is the subject of the present invention. The device 1100 for cleaning a window 101 comprises at least: - a grip handle 1105 for a user capable of being connected to a pole, - a 1110 tank of wash water, - a 1115 wastewater tank and - a 1120 cleaning head.

[0106] It can be seen, in [Fig.3], that the cleaning head 1120 is integral with the gripping handle 1105 and comprises: - an 1125 drive motor, - a 1130 friction roller, - a 1140 wash water injector and - a 1150 wastewater suction chute.

[0107] It is noted, in [Fig.3], that the friction roller 1130 comprises a shaft 1135 driven by the motor 1125. Furthermore, in [Fig.3], the cleaning head 1120 of the device 1100 includes: - a first pipe 1145 connecting the wash water injector 1140 and the wash water tank 1110, and - a second pipe 1155 connecting the wastewater suction chute 1150 and the wastewater tank 1115.

[0108] It is noted that, in figures 4, 5, 7 and 8, the wash water tank 1110 and the waste water tank 1115 are not shown.

[0109] In embodiments, such as that shown in Figures 3 and 6, the handle 1105 comprises an ergonomic portion, that is to say adapted to a manual grip carried out by a user. In particular, such an ergonomic portion has a curved part.

[0110] In embodiments, such as those shown in Figures 3 to 8, the gripping handle 1105 is secured to the cleaning head 1120, in a non-removable manner.

[0111] Preferably, as visible in figures 3 and 6, the part formed by the cleaning head, 1120 and 1320, and a portion of the gripping handle, 1105 and 1305, has a longitudinal profile in the shape of a swan's neck.

[0112] It can be seen, in figures 3 to 8, that the gripping handle, 1105 and 1305, is hollow longitudinally in order to at least partially or even completely enclose, in other words to envelop: - part of the electrical connections necessary for the operation of the device, 1100, 1200, 1300 and 1500, - a part of the first pipe 1145 connecting the wash water injector 1140 and the wash water tank 1110.

[0113] Furthermore, a portion of the wastewater suction chute 1150 is preferably included in the gripping handle, 1105 and 1305.

[0114] In embodiments, such as those shown in Figures 3 to 8, the gripping handle, 1105 and 1305, comprises a lever 1106 for injecting wash water.

[0115] In embodiments (not shown), the injection lever has the same function as a liquid sprayer commonly used in the packaging of household products, for example. In particular, such a sprayer injects the washing water punctually according to the pressure or release movement exerted by the user on the injection lever.

[0116] In other embodiments, the handle 1106 comprises a means 1107 for activating and / or deactivating the injection of wash water. Such an activation and / or deactivation means 1107 is actuated by the injection handle 1106. For example, the injection activation and / or deactivation means 1107 is a microcontroller. An activation means is configured to activate the injection of wash water. washing according to the signal received by the injection lever 1106. On the contrary, a deactivation means is configured to deactivate the injection of washing water according to the signal received by the injection lever 1106. An injection activation and deactivation means 1107 is configured to perform these two functions.

[0117] [Fig. 8], which is not to scale, shows a schematic view of an embodiment of the cleaning device 1500. The device 1500 comprises a cleaning head 1520 comprising a connector 1502. Such a connector 1502 secures the cleaning head 1520 to the gripping handle 1105. It is noted that the connector comprises a movable connection 1503.

[0118] In embodiments, such as that shown in [Fig.8], the movable connection 1503 of the connector 1502 is a pivot connection with axis C parallel to the axis Z of rotation of the friction roller 1130. Such a connector is, for example, known in the field of vacuum cleaners, in particular allowing rotation of a suction head of a vacuum cleaner.

[0119] In other embodiments (not shown), the movable connection 1503 of the connector 1502 is a pivot connection with an axis perpendicular to the Z axis of rotation of the friction roller 1130.

[0120] In variants (not shown), the movable connection 1503 of the connector 1502 is a ball joint.

[0121] In embodiments, such as those shown in Figures 4, 5, 7 and 8, the cleaning head 1120 has a flared shape. Note that the flare is oriented opposite the junction with the grip handle, 1105 and 1305.

[0122] In embodiments, such as those shown in Figures 3 to 8, the cleaning head, 1120, 1220, 1320 and 1520, comprises a blade 1102 called a “squeegee”.

[0123] In these embodiments, the scraper 1102 extends at least partially over a portion of the chute 1150 remote from the friction roller 1130. In particular, the scraper 1102 extends over the entire portion of the chute 1150 remote from the friction roller 1130.

[0124] In embodiments, such as those shown in Figures 3 to 8, the squeegee 1102 is removable. In particular, the insertion or detachment of the squeegee 1102 on the cleaning head, 1120, 1220, 1320 and 1520, is carried out by sliding the squeegee along an axis B. Preferably, the cleaning head, 1120, 1220, 1320 and 1520, comprises a housing along the axis B of a shape complementary to a longitudinal portion of the squeegee 1102.

[0125] Preferably, the squeegee 1102 is made of a flexible material and in particular elastically deformable. For example, such a flexible material is rubber or any polymer or flexible material known to those skilled in the art.

[0126] In embodiments, such as that shown in [Fig.l 1], a device for cleaning 1700 includes a blade called squeegee 1702 called “finishing”. Note that the squeegee 1702 includes a bar 1704 supporting a rubber 1703. Preferably, the rubber 1703 is removable.

[0127] In embodiments, such as that shown in [Fig.l 1], a connection between the squeegee 1702 and a portion of the cleaning head is a pivot connection along an axis B. It is noted that such a connection comprises a return means 1705 towards a predetermined angular position of rotation of the squeegee 1702.

[0128] In other words, in [Fig. 11], the bar 1704 of the squeegee 1702 is fixed along the axis B and has a freedom of rotation along the axis B represented by a double arrow. The rotation of the bar 1704 according to a predetermined angle is reversible by the action of the return means 1705. For example, the angular position associated with this freedom of rotation is between 1 degree and 45 degrees, more preferably between 1 degree and 20 degrees. In particular, the bearing angle, and therefore the angular position, of the bar 1704 on the window 101 varies according to the mechanical constraints exerted during the use of the device 1700 then returns to the initial angular position. It is noted that the initial angular position, corresponding to a predetermined angular position, is defined for example for an angle of rotation substantially equal to 0 degrees. This reversibility of rotation is obtained by the return means 1705. For example, such a return means 1705 is a spring.It is noted that the angle of freedom in rotation, or angular position, is conditioned by the return means 1705 and in particular according to its elastic properties.

[0129] In these embodiments, the angle of rotation along the axis B of the bar 1704 varies depending on the positioning of the cleaning device 1700 and the force applied to the window 101 by the user. Thus, when the window 101 has a horizontal or vertical lower frame 1701 (not shown), and for example perpendicular to the window 101, the pivoting nature of the bar 1704 makes it possible to maintain the support of the rubber 1703 against the window 101 and at the junction between the window 101 and the frame 1701. An optimal cleaning finish is therefore obtained.

[0130] In embodiments, such as those shown in Figures 3 to 8, the cleaning head, 1120, 1220, 1320 and 1520, comprises at least one friction plate, 1103 and / or 1104. It is noted that such a friction plate, 1103 and / or 1104, is configured to come into contact with the window 101. In particular, at least a portion of the friction plate, 1103 and / or 1104, is aligned with a tangent of a directrix of the cylinder truncated formed by the friction roller, 1130 and 1330. Such a tangent comprises at least one point of contact with the window 101 to be cleaned.

[0131] Preferably, a friction plate, 1103 and / or 1104, extends at least partially along a generatrix of the cylinder trunk formed by the roller, 1130 and 1330, of friction. Even more preferably, a plate, 1103 and / or 1104, extends over the entirety of a generatrix of the cylinder trunk formed by the roller, 1130 and 1330, of friction.

[0132] In embodiments, the surface for bringing the friction plate, 1103 and / or 1104, into contact with the window 101 has a surface comprising fibers, preferably natural fibers. Such fiber friction plates are known to those skilled in the art.

[0133] [Fig. 5], which is not to scale, shows a schematic view of an embodiment of the cleaning device 1200. The device 1200 comprises a cleaning head 1220 comprising: - a pressure sensor 1201 configured to capture pressure exerted on the friction roller 1130 when the roller 1130 comes into contact with the window 101, - a detector 1202 for crossing a predetermined pressure as a function of the pressure captured and - a means 1203 for activating and / or deactivating the drive motor 1125 depending on the detected crossing.

[0134] In embodiments, such as that shown in [Fig.5], the sensor 1201 interacts with the activation and / or deactivation means 1203 via the detector 1202.

[0135] In embodiments, the means 1203 for activating or deactivating the drive motor 1125 is a microcontroller. An activation means 1203 is configured to activate the motor 1125 depending on the signal received by the detector 1202. On the contrary, a deactivation means 1203 is configured to deactivate the motor 1125 depending on the signal received by the detector 1202. An activation and deactivation means 108 of the motor 1125 is configured to perform these two functions.

[0136] It is noted that, for example, a predetermined pressure corresponds to a minimum compression pressure of the friction roller 1130 on the window 101.

[0137] It can be seen in Figures 3 and 6 that the cleaning head 1120 and 1320 comprises a drive motor 1125. Such a motor 1125 drives a rotation of the shaft 1135 of the roller 1130 and 1330 along the Z axis.

[0138] It can be seen, in figures 4, 5 and 7 and 8, that the roller, 1130 and 1330, comprises a gear 136 secured to the shaft 1135 and configured to be driven in rotation by a gear (not shown) of the drive motor 1125. It can be noted that the gear 136 of the roller, 1130 and 1330, therefore ensures the rotation of the shaft 1135.

[0139] In embodiments, such as those shown in Figures 3 and 6, the drive motor 1125 is configured to rotate the friction roller 1130 so as to direct the wastewater toward the suction chute 1150.

[0140] It is noted that, in these embodiments, the rotation of the roller 1130 is conditioned by the rotation of the gear of the drive motor 1125. Thus, such a gear is adjusted so as to favor this preferential rotation.

[0141] In embodiments, the motor 1125 is electrically powered. Such electrical power is provided, for example, by a battery (not shown) connected to the motor 1125. Note that the battery is connected to the motor 1125 by an electrical cable 1126 shown in FIGS. 3 and 6.

[0142] Figures 6 and 7, which are not to scale, show two schematic views of an embodiment of the cleaning device 1300. The device 1300 comprises a friction roller 1330 having orifices 1301 for the passage of washing water.

[0143] Preferably, as visible in [Fig.7], the orifices 1301 for the passage of the washing water are present along the friction roller 1330.

[0144] In embodiments, such as that shown in Figures 6 and 7, an outlet of a wash water injector 1340 is arranged in an internal volume of the friction roller 1330 delimited by the orifices 1301 for the passage of wash water. In these embodiments, and when the roller has a friction thickness mentioned below, the wash water injected by the injector 1340 passes through the orifices 1301 and preferentially soaks the friction thickness first and then soaks the friction plates, 1103 and 1104.

[0145] In embodiments, the friction roller, 1130 and 1330, comprises a friction thickness at least partially enclosing the external surface of the roller and configured to be brought into contact with the window 101.

[0146] Preferably, the friction thickness is flexible and in particular deformable under the action of mechanical stress, for example, when pressure is exerted by a user.

[0147] In embodiments, the friction thickness is a layer which comprises fibers, for example natural fibers. Preferably, the fibers of the friction thickness have reduced hardness and abrasiveness in order to avoid scratching the window 101. Such fibers are known to those skilled in the art.

[0148] Thus, the fibrous friction thickness limits the wear of the window 101 caused by the friction of the roller, 1130 and 1330, while ensuring the cleaning of the window 101.

[0149] It is noted that, when the flexible friction thickness is soaked with washing water, the pressure exerted by the user has the effect of crushing the friction thickness against the window 101. In this case, the point of contact between the friction thickness and the window 101 is generally aligned with the other points of contact between the friction plates, 1103 and 1104, and the window 101. Thus, in these embodiments, an overall contact and friction surface is formed during use of the device.

[0150] In embodiments, the wash water injector, 1140 and / or 1340, is a injection nozzle.

[0151] In embodiments, such as that shown in [Fig.3], the injector 1140 diffuses wash water onto the external surface of the friction roller 1130.

[0152] In variants, such as that shown in [Fig.6], the injector 1340 diffuses washing water inside the friction roller 1130, as mentioned previously.

[0153] In embodiments, such as those shown in Figures 3 to 8, the wash water injector is controlled by a control means corresponding to the injection lever 1106, as mentioned previously.

[0154] It is noted that the first pipe 1145 for circulating the wash water can be in several nestable or clippable parts, but also in a single continuous part.

[0155] In embodiments, such as those shown in Figures 3 and 6, the suction chute 1150 is connected to the wastewater tank 1115 by the second pipe 1155. The wastewater tank 1115 is, for example, connected to a suction means. Such a suction means is configured to put the wastewater tank 1115 under vacuum and carry out the suction.

[0156] In embodiments, the chute comprises at least one solid filter along the wastewater passage.

[0157] It is noted that the second pipe 1155 for circulating wastewater can be in several nestable or clippable parts, but also in a single continuous part.

[0158] In embodiments, at least one of the wash water tank 1110 and the waste water tank 1115 is attached to the gripping handle 1105. Such embodiments are suitable, for example, for devices of reduced size, in particular not exceeding a certain mass and for cleaning operations not requiring a significant quantity of water.

[0159] In these embodiments, the reservoirs, 1110 and / or 1115, are, for example, rechargeable or removable and therefore replaceable.

[0160] In [Fig.9], we observe the device 1600 comprising a backpack 1602 which comprises the tank 1610 of washing water and the tank 1615 of waste water. Such a backpack 1602 is also called a “back element”.

[0161] In variants (not shown), the backpack comprises only one reservoir from among the wash water reservoir 1610 and the waste water reservoir 1615.

[0162] In embodiments, a connection between the second wastewater conduit 1155 and the wastewater tank 1615 includes a filter capable of filtering solids present in the wastewater before introducing the wastewater into the tank 1615. Thus, solid fouling of the wastewater tank 1615 is limited.

[0163] In embodiments, the reservoirs, 1610 and / or 1615, juxtaposed in the backpack 1602 form an assembly covering the entire back of the user. Thus, their shape contributes to a uniform distribution of the loads supported by the back of the user.

[0164] Figures 9 and 10, which are not to scale, show a schematic view of an embodiment of the cleaning device 1600. Figures 9 and 10 show that the gripping handle and the cleaning head are not shown. The device 1600 further comprises a backpack 1602. The backpack 1602 comprises: - a tank 1610 for washing water, - a tank 1615 for waste water, - a means 1612 for circulating washing water and - a means 1609 for sucking up waste water.

[0165] In embodiments, such as that shown in [Fig.9], the backpack 1602 comprises two support straps 1603. It is noted that, when using the device 1600, the straps 1603 rest on the shoulders of the user.

[0166] In variants, the support straps correspond to two hooks of adequate width for the user's shoulders to pass through.

[0167] In embodiments, such as that shown in [Fig.9], the backpack 1602 comprises two straps 1604, arranged in the middle of the length and on either side of the backpack 1602. It is noted that such straps 1604 respectively comprise two parts that can be clipped into one another and are therefore connectable, in a manner similar to a seat belt, for example. Preferably, the connected straps 1604 encircle the user's chest, and are also called "chest attachment".

[0168] In embodiments, such as that shown in [Fig.9], the backpack 1602 also comprises two straps 1605, arranged in the lower part of the length and on either side of the backpack 1602. It is noted that such straps 1605 respectively comprise two parts that can be clipped into one another and are therefore connectable, in a manner similar to a seat belt, for example. Preferably, the connected straps 1605 encircle the lower part of the user's torso, and are also called "belt attachment".

[0169] In embodiments, such as that shown in [Fig.9], the backpack 1602 comprises a mattress 1607 covering the portion closest to the user's back. Thus, the user's back rests on the mattress 1607, which increases the comfort of the backpack 1602 when worn.

[0170] In embodiments, such as that shown in Figures 9 and 10, the backpack 1602 comprises in the upper part two insertion housings, respectively for the tank 1610 of washing water and for the tank 1615 of waste water.

[0171] It can be seen in Figures 9 and 10 that the backpack comprises, in the lower part, a volume delimiting a compartment 1606. In particular, compartment 1606 comprises: - a means of circulation 1612 of wash water and - a means of suction 1609 of waste water.

[0172] In embodiments, the washing water circulation means 1612 comprises a washing water propulsion motor 1616. Preferably, the washing water propulsion motor 1616 is electrically powered by an electric cable 1618.

[0173] In embodiments, the means 1612 for circulating wash water comprises, in a complementary manner, a battery 1611 for supplying power to the propulsion motor 1616, increasing the autonomy of the device 1600.

[0174] It is noted, in [Fig. 10], that the circulation means 1612 of washing water, and in particular the propulsion motor 1616, is connected to the first pipe 1145 via the washing water tank 1610. Such a circulation means 1612 is configured to circulate the washing water to the washing water injector. For example, such circulation of the washing water is carried out by pressurizing the interior of the washing water tank 1610 causing water propulsion.

[0175] In embodiments, the wastewater suction means 1608 comprises a wastewater suction motor 1609. Preferably, the wastewater suction motor 1609 is electrically powered by an electric cable 1619.

[0176] In embodiments, the wastewater suction means 1608 additionally comprises a battery 1617 of the suction motor 1609 increasing the autonomy of the device 1600.

[0177] It is noted, in [Fig. 10], that the wastewater suction means 1608, and in particular the wastewater suction motor 1609, is connected to the second pipe 1155 via the wastewater tank 1615. Such a suction means 1608 is configured to exert a vacuum, in particular inside the wastewater tank 1615, and therefore cause the suction of the wastewater from the suction chute towards the wastewater tank 1615.

[0178] In embodiments, such as that shown in [Fig.10], compartment 1606 comprises two switches: - a switch 1614 configured to trigger or stop the electric current supplying the means 1612 for circulating wash water and - a switch 1613 configured to start or stop the electric current supplying the wastewater suction means 1608.

[0179] In embodiments, the electrical energy powering the backpack is also used for powering the 1125 friction roller drive motor.

[0180] In embodiments, the backpack further comprises photovoltaic cells arranged on the surface of the backpack furthest from the user. Thus, all or part of the electrical energy necessary for the operation of the device 1600 comes from the photovoltaic cells.

[0181] In embodiments (not shown), when the user performs rope work with the device 1600, a preferably semi-rigid spring is clipped onto the user's seat and backpack, and configured to relieve the weight of the backpack which exerts pressure on the user's back.

[0182] It is noted that all the embodiments and variants described for a particular device, 1100, 1200, 1300, 1500 or 1600, of FIGS. 3 to 10 are also valid for another device, 1100, 1200, 1300, 1500 or 1600, unless otherwise stated.

[0183] Benefits provided

[0184] According to a first aspect, the present invention relates to an automatic telescopic pole for supporting a window cleaning device, comprising: - a lower gripping arm for a user; - a first arm movable in sliding relative to the lower arm and connected to the cleaning device by a connection element; and - a means for sliding the first movable arm relative to the lower arm, comprising: - at least one wheel driven in rotation, the rotation of the wheel causing the first movable arm to slide, - a motor for driving the rotation of said wheel and - a means of activating and / or deactivating the drive motor.

[0185] Thanks to these provisions, the pole allows easy access to a plurality of window heights without effort on the part of the user such as a maintenance worker. In particular, the telescopically and automatically deployable pole allows the user to avoid having to manually modify the length of the pole. Thus, the user has more precise access to variable window heights, saving time. In particular, the telescopic pole allows the user to reach heights and angles on the window to be cleaned that are initially difficult to access.

[0186] In optional embodiments, the pole further comprises a handle called a "pressure handle" fixed in the upper half of the gripping arm.

[0187] Thanks to these arrangements, the pole allows the user to exert, using a lever arm, additional pressure on the cleaning device and therefore on the window to be cleaned. Thus, the cleaning of the window is more efficient.

[0188] In optional embodiments, the pole further comprises: - at least a partial hoop secured to the lower gripping arm and - a branch fixed to the hoop, supporting a wheel driven in rotation and keeping the wheel resting on the first movable arm.

[0189] Thanks to these arrangements, the branch and wheel assembly participates in guiding and maintaining the first sliding mobile arm. Thus, the stability of the first mobile arm, during sliding, is improved.

[0190] In optional embodiments, at least one element among the lower gripping arm and the first movable arm has at least one longitudinal section for passing electrical power supply wires.

[0191] Thanks to these arrangements, the power supply wires of the pole are included in an internal volume. For example, when the cleaning device coupled to the pole is electrically powered, these arrangements make it possible to prevent such wires from being free near the device. Thus, user safety is increased while ensuring maximum compactness of the pole.

[0192] In optional embodiments, the pole further comprises a reel for supplying electrical wires, disposed on a lower end of the lower gripping arm.

[0193] Thanks to these arrangements, the electrical wires are wound and unwound depending on the deployment or retraction of the pole and therefore according to the user's needs. Thus, the risks of tangling or pinching the electrical wires are limited.

[0194] In optional embodiments, the connection element further comprises a second arm movable in sliding relative to the first movable arm,

[0195] the pole further comprising a second means for sliding the second movable arm relative to the first movable arm, comprising: - at least one second wheel driven in rotation, the rotation of the second wheel causing the second movable arm to slide, - a second motor for driving said second wheel in rotation and - a means of activating and / or deactivating the second drive motor.

[0196] Thanks to these provisions, the pole allows greater access to a number of window heights. Furthermore, for an equal pole deployment length, a pole with two movable arms is more stable than a pole with only one movable arm. In particular, the end of the second arm connected to the cleaning device is optimally maintained.

[0197] In optional embodiments, the pole further comprises a self-contained power supply.

[0198] Thanks to these provisions, the pole allows the user to avoid the need for a power supply near the pole. Thus, the pole can be used in a large number of different environments without constraints power supply. Furthermore, these provisions make it easier for a user to move around.

[0199] In optional embodiments, the pole further comprises at least two internal connection pipes connected to the cleaning device, one internal pipe being a wash water injection pipe and the other pipe being a waste wash water suction pipe.

[0200] Thanks to these provisions, the compatibility of the pole with a cleaning device, combining injection and suction of waste water, is improved. Thus, the compactness and practicality of the pole are optimal.

[0201] In optional embodiments, the pole further comprises a lever for injecting wash water into the injection pipe.

[0202] Thanks to these provisions, the pole allows the user to control, in real time and dynamically, the washing water injected into the cleaning device. Water consumption is therefore limited directly by the user. Thus, significant water savings are achieved in particular.

[0203] According to a second aspect, the present invention relates to a cleaning system comprising a pole which is the subject of the invention and a cleaning device by injection of washing water and suction of used washing water.

[0204] The aims, advantages and particular characteristics of the system which is the subject of the present invention being similar to those of the pole which is the subject of the present invention, they are not recalled here.

[0205] In optional embodiments, the cleaning device comprises at least: - a grip handle for a user capable of being connected to a telescopic pole, 100 and / or 200, - a wash water tank, - a wastewater tank and - a cleaning head, attached to the grip handle, comprising: - a drive motor, - a friction roller comprising a shaft driven by the motor, - a wash water injector connected to the wash water tank by a first pipe and - a wastewater suction chute connected to the wastewater tank by a second pipe.

[0206] Thanks to these provisions, the cleaning system comprising the cleaning device makes it possible to implement window cleaning which combines mechanical friction with a roller in the presence of washing water and suction of the waste water. In particular, the cleaning device makes it possible to limit the effort provided by the user, for example on the arm and wrist, to clean a window. In addition, the cleaning device makes it possible to limit the occasional or regular exposure of the user to washing water and wastewater. Such exposure corresponds, for example, to skin and / or ophthalmic splashes. The risks of skin allergy, irritation or lesions are therefore reduced.

[0207] Furthermore, by implementing suction, the cleaning device makes it possible to limit the discharge and flow of wastewater. An additional step of cleaning the wastewater that has flowed and been discharged, for example onto the ground, is therefore avoided.

[0208] Thus, easy, quick and efficient cleaning is achieved when using such a cleaning device.

[0209] In optional embodiments, the cleaning head of the cleaning device further comprises a blade called a "squeegee", extending at least partially over a portion of the chute remote from the friction roller.

[0210] Thanks to these provisions, the squeegee allows for an adequate finish to the cleaning of the window. Thus, in a single pass and without excessive effort, the user cleans a portion of the window. The efficiency of the cleaning device is thus improved.

[0211] In optional embodiments, a connection between the squeegee and a portion of the cleaning head is a pivot connection along an axis, this connection comprising a means for returning the squeegee to a predetermined angular position of rotation.

[0212] Thanks to these arrangements, the cleaning device allows for an optimal finish of the cleaning of the window comprising, for example, a horizontal or vertical frame. In particular, at the junction between the window and the frame, the partially rotating free squeegee passes continuously from the window to the junction making it possible to remove most or even all of the used washing water from the surface of the window. In particular, at such a junction and when the squeegee returns to its initial position thanks to the return means, the used washing water is directed towards the suction chute by the squeegee.

[0213] In optional embodiments, the cleaning head of the cleaning device further comprises at least one friction plate configured to contact the glass.

[0214] Thanks to these arrangements, friction on the glass and therefore additional mechanical de-fouling is achieved by the friction plate. The friction of the roller is therefore supplemented by the friction plate. Thus, more effective de-fouling of the glass is achieved.

[0215] In optional embodiments, the cleaning device further comprises: - a pressure sensor configured to sense pressure exerted on the roller of friction when the roller comes into contact with the glass, - a detector for exceeding a predetermined pressure depending on the pressure captured and - a means of activating and / or deactivating the drive motor depending on the detected crossing.

[0216] Thanks to these provisions, the cleaning device allows activation of the rotation of the roller only when it comes into contact with the window. In particular, the risks of uncontrolled projection of water containing washing products by rotation of the roller are therefore limited. Furthermore, deactivating the rotation makes it possible to avoid continuous operation of the roller and therefore limits the energy consumption, for example in the form of electrical energy, of the cleaning device. Thus, the use of the cleaning device is easier and less energy-intensive.

[0217] In optional embodiments, the drive motor of the cleaning device is configured to rotate the friction roller so as to direct wastewater toward the suction chute.

[0218] Thanks to these provisions, the cleaning device allows rotation with a specific orientation towards the suction chute and therefore direct suction of the wastewater. More efficient suction of the wastewater is therefore achieved. Thus, uncontrolled discharges of wastewater are effectively limited.

[0219] In optional embodiments, the friction roller has orifices for the passage of wash water.

[0220] Thanks to these provisions, the circulation of the wash water is facilitated. Thus, the distribution of the injected wash water is achieved in a more homogeneous and optimal manner.

[0221] In optional embodiments, an outlet of the wash water injector is arranged in an internal volume of the friction roller delimited by the wash water passage orifices.

[0222] Thanks to these arrangements, all of the washing water is brought into contact with the friction roller, circulating in particular through the passage orifices. The combination of the roller and contact with all of the washing water therefore allows for more effective friction of the roller and thus optimal defouling.

[0223] In optional embodiments, the gripping handle further comprises a wash water injection lever, the cleaning device comprising a means for activating and / or deactivating the injection of wash water actuated by the injection lever.

[0224] Thanks to these provisions, the cleaning device allows the user to control, in real time and dynamically, the injected wash water. Water consumption is therefore limited directly by the user. Thus, significant savings water are notably carried out.

[0225] In optional embodiments, the cleaning head further comprises a connector with the gripping handle comprising a movable connection.

[0226] Thanks to these arrangements, the mobility of the cleaning head is greater. Such mobility is ensured, for example, by a pivot connection or a ball joint. Thus, the orientation of the cleaning head is easily achieved, for example, according to the needs of the user.

[0227] In optional embodiments, the cleaning system further comprises a backpack comprising: - the wash water tank, - the wastewater tank, - a means for circulating wash water connected to the first pipe and configured to circulate the wash water and - a wastewater suction means connected to the second pipe and configured to exert a vacuum,

[0228] the wash water and waste water tanks being connected with the cleaning device via the pole.

[0229] Thanks to these provisions, the largest and heaviest elements of the cleaning system are supported by the user's back. In particular, when large volumes of water are consumed during cleaning, the use of the backpack makes it possible to distribute and support the masses of the different elements of the cleaning system. Furthermore, the backpack allows the user to move more easily while supporting the different loads. The mobility of the cleaning system is therefore increased, allowing in particular greater freedom of movement for the user. For example, such a cleaning system allows compatibility with rope work by a professional.
